Abstract: Multi-sensory integration is a fundamental problem for any embodied cognitive system -- both biological and artificial. Here, we pursue a network approach to model the flow of evoked activity, initiated by stimuli at primary sensory regions. In particular, we use the Asynchronous Linear Threshold (ALT) diffusion model on the mesoscale cortical connectome of the mouse. The ALT model captures how evoked activity that originates at a given region of the cortex “ripples through” other brain regions. Our results show that a small number of brain regions (the Claustrum being at the top of the list) integrate almost all sensory information paths, suggesting that the cortex relies on an ``hourglass architecture'' to integrate and compress multi-sensory information before utilizing that lower-dimensionality representation in association regions and tasks.
